Both of these are ionic compounds. Their solubility would depend on two factors. 1. Lattice energy 2. read more
The more covalent character is exhibited in NaI than in NaCl making it a weaker bond in accordance with Fajans rules . Bond enthalpy of NaI is lesser than that of NaCl(it could be seen as a consequence or as a proof on the basis of chemical energetics). read more
• Sodium chloride is more abundant than sodium iodide. • NaI is more soluble in water than NaCl. • Sodium chloride is commonly known as salt and sodium iodide is an additive to salt to reduce the iodine deficiency in human. read more
Sodium chloride and sodium bromide being less soluble in acetone get precipitated from the solution and can be removed by filtration. This also prevents the backward reaction to occur according to Le Chatelier's principle. read more
